Accessing IMAP folders problem.

[FeraTechInc]

So I followed the Ubuntu Edgy perfect setup and installed ISPConfig. I set up an IMAP account and on my server run Thunderbird. What Thunderbird does is, it downloads all my mail from my 3 different accounts into 1. Then I have a PC and a Desktop which I use to actually check my mail.

The problem is that my PC and Laptop both have a problem when connecting to the IMAP account. They frequently time out. It seems like there is a restricted number of users that can be connected to that account at a time.

Is there a way to do this or an alternative way to get all my mail into one folder and then sync it between 3 difference PC's.

Do you get any error messages in the mail log? Does your server use Maildir or Mbox format for storing the emails?

Here is my log file. There aren't any errors, just a strange connection from 204.228.237.29 which shouldn't be there.

Does your server use Maildir or Mbox format for storing the emails?

[FeraTechInc]

Honestly I am not sure. However, I did opt not to have Postfix deliver mail to the maildir and decided to use ISPConfig system instead.

Is there any way I can double check?

[martinfst]

ISPConfig uses the regular Postfix installation. So if you skipped the postfix setup, you have missed a couple of essential steps. Please reread the howto and do the postfix (+sasl and the rest) parts.

[FeraTechInc]

I did not skip the postfix setup. My mail would not work at all if it was the case. This is the part of the setup I skipped:

 If you do not want to use ISPConfig, configure Postfix to deliver emails to a user's Maildir*:

postconf -e 'home_mailbox = Maildir/'
postconf -e 'mailbox_command ='
/etc/init.d/postfix restart

As you can specifically see this is only to use the maildir.

[martinfst]

If you have followed the default howto for all other tools, those will assume Maildir format. Which means you shouldn't have skipped these steps. Please execute those commands to complete your installation.

After restarting Postfix, I'm not sure if you have to re-create the mail account. That may be the case. Also sent an initial 'welcome' email to this account, or use the 'maildircreate' command to create the Maildir structure for this user. Postfix will automagically created the required directories, but the IMAP/POP servers will fail if the directory structure is not there.
